BTC/USDT: Which One Is Which?
Which side of the slash is which, what you buy vs what you pay with, how buy and sell map to it, and how the quote coins differ — before you pick a pair.
Binance spot trading for beginners: read the rules before you place an order
Don't rush the order. Learn what spot is, the parts of the screen, order types, minimum order size, and the beginner traps to avoid.
Rules · how orders really work
GTC, IOC and FOK — what time in force actually does to your order
It sets how long the order lives, not the price it gets. What happens to the unfilled part under IOC and FOK, and why a killed order logs as Expired.
Market-order slippage on Binance: what it is, how to lose less
Your fill price isn't the price you saw — that gap is slippage. Why it happens, when it's worst, and how limit orders and reading depth cut it down.
Binance OCO Orders: Why They Get Rejected
An OCO pairs take-profit and stop-loss so only one triggers. For sells the price order is strict — limit above market, market above trigger.
Trigger price vs limit price on a stop order
Trigger wakes the order up; limit gets it filled. Cross the two and it never goes through. A plain-English look at how they split the work — plus stop-market vs stop-limit.
Binance Order Types: Limit, Market, Stop and OCO Explained
Limit, market, stop and OCO orders - what each does, when it fits and the pitfalls. A plain-English read on the rules so you don't set the wrong order.
Maker vs Taker: What They Are and How They Differ
A plain-English look at how maker and taker orders differ inside the order book, and how each ties to fill speed and cost.
Life of an Order: How Binance Matching Works
What happens after you hit confirm. The order book, price-time priority, fills or queueing, and partial fills — walked through step by step.
Safety · check before you act
Why your order gets rejected in a listing's first minutes
Rejected and unfilled fail at different points. The valid price range is built from an average of previous trade prices, and on a new listing that average is still being made. Quantity and notional get their own checks, and a market order has no price of its own.
Fat-fingered a limit price? Why it filled at once or got rejected
A limit buy priced above the lowest ask trades immediately, level by level, never above your limit. Priced far enough off the market, it fails the pair's price rules. The real bands on major pairs, how to read which rule you hit, and where a fat-finger shows up.
The 25% / 50% / 100% bar on Binance's order form — what it's actually a percentage of
It measures your available Spot balance, not your position. Buy side counts your quote currency, sell side counts your coin, with extra checks before using 100%.
The Order Mistakes Beginners Make Most Often
Wrong pair, market slippage, limit orders that never fill, reversed TP/SL, all-in with no stop, chasing pumps, leverage — why each one happens and how to sidestep it.
Fixes · when you're stuck
Binance partial fill: what it means and what to do with the rest
'Partially Filled 6/10' isn't a glitch — part filled, the rest is still in line. Whether to wait, cancel or modify, and how fees and average price are counted.
Why your Binance limit order won't fill
Sitting there unfilled? Don't rush to cancel. Usually it's not a glitch — it's queue rules. How to tell why, whether to touch it, and why not to chase.
Cancelling and Modifying Orders on Binance (and Whether to Chase the Price)
How cancel and modify actually work, what to do after a partial fill, and why chasing the price often makes things worse. Independent, unofficial guide.
Binance buy button greyed out, or a minimum-order notice? Here's what's going on
Button won't click, or a minimum-order notice pops up? Usually not a glitch — your order just doesn't meet the rules. Common causes, one by one.

Bought crypto but can't find it? Where it lands and whether you can sell right away
How you bought decides where the coins sit: spot orders stay in Spot, P2P goes to Funding, card buys need a look under Overview. The 24-hour P2P hold limits withdrawals, not trading.
Where Your USDT Goes After You Sell, and How to Read Your Balances and Trades
Sold on Binance but the balance won't add up? Tell the Spot and Funding wallets apart, find your trade and order history, and see why open orders lock funds.
Reading your average buy price and P&L
How average price is worked out, why it shifts when you buy in batches, which column shows unrealised P&L, how fees raise your cost, and why the screen never matches your maths.
